braking in good time, and for stayin ginl ane.
Always adapt your drivin gs tyle to suit the pre-
vailing road and weather condition sa nd main-
tain as afe distance from the vehicle in front.
Drive carefully.
The drivin gs afet ys ystems described only work
as effectively as possible when there is ade-
quate contac tb etwee nt he tires and the road
surface. Pay particular attention to the informa-
tion regarding tires, recommended minimum
tir et re ad depth se tc .int he "Wheels and tires"
section ( Y
page 260).
In wintry drivin gc onditions, always use winter
tires (M+S tires) and if necessary, sno wc hains.
Only in this way will the drivin gs afet ys ystems
described in this section work as effectively as
possible.
ABS (Anti-lock Braking System)
Genera li nformationAB Sr egulates brak ep ressure in such aw ay that
the wheels do not lock when you brake. This
allows you to continue steerin gt he vehicle when
braking.
The % AB Sw arnin gl amp in the instrument
cluster light supw hen the ignition is switched
on. It goes out when the engin eisr unning.
AB Sw ork sf rom as peed of about 5m ph
(8 km/h), regardless of road-surfac ec onditions.
AB Sw ork sons lippery surfaces, even when you
only brak eg ently.
Important safet yn otes
i Observe the "Importan ts afet yn otes" sec-
tion ( Y

ing characteristics would be severely affec-
ted. There is an increased danger of skidding
and accidents.
Drive on carefully. Have AB Sc hecked imme-
diately at aq ualified specialis tw orkshop.
When AB Sism alfunctioning, other systems,
including drivin gs afet ys ystems, will also becom ei noperative .O bserve the information
on the AB Sw arnin gl amp ( Y
page 204) and dis-
play messages which may be shown in the

Brakes X
If ABS intervenes: continue to depres st he
brak ep edal vigorously until the braking sit-
uation is over. X
To make af ull brake application: depress
the brak ep edal with full force.
If AB Si ntervenes when braking, you will feel a
pulsing in the brak ep edal.
The pulsatin gb rak ep edal can be an indication
of hazardous road conditions, and function sasa
reminder to tak ee xtra care while driving.
BAS (Brake Assist System)
Genera li nformationBA So perates in emergenc yb raking situations.
If you depres st he brak ep edal quickly, BAS
automatically boost st he braking force, thus
shortening the stopping distance.
Important safet yn otes
i Observe the "Importan ts afet yn otes" sec-

G WARNING
If BA Sism alfunctioning, the braking distance
in an emergenc yb raking situation is
increased. There is ar isk of an accident.
In an emergenc yb raking situation, depress
the brak ep edal with full force. AB Sp revents
the wheels from locking.
Braking X
